Each Friday we round up the big conversations in tech and culture during the week that was. We also revisit the work that appeared on this blog, and highlight what we're reading from our fellow technology writers and observers at other organizations.

Tom Bowman reported on technology being developed to give special ops troops Iron Man-like suits to protect them in battle. Elise followed up on the hackable Japanese toilet and learned that its app collects perhaps a bit TMI. Steve Henn examined the backlash against Twitter after threats and abusive messages targeted prominent women in the U.K. And Steve says another backlash is feared — this one against the new wireless emergency alert system after Amber Alerts startled millions of mobile phone users.

Daniel Hajek reported on advertisers looking for an audience, six seconds at a time, on the Vine video app. Leslie Bradshaw, chief operating officer at the startup Guide, wrote about how women are having a bigger influence at the top of the tech industry, in their own way. And, finally, our weekly innovation pick was the Kite Patch, a sticker that hopefully makes you invisible to mosquitoes.

The latest mash-up toy is here. Chad Hurley and Steve Chen, who brought YouTube to the world, have launched MixBit, an app that looks to do Vine and Instagram videos one better. Their new app lets you mix, edit and collaborate on videos — even those who didn't shoot — to create and share stories.

That's right, blame the machine. Some Xerox copiers are changing numbers on documents, according to a German computer scientist who found that scans he made of construction plans had altered room dimensions. Xerox said the problem is limited to scans made under a certain setting.
